QTS750C-20.000MBP-T

Overview

The QTS750C-20.000MBP-T is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by QST. It operates at a nominal frequency of 20 MHz with a CMOS output interface. The device requires a 3.3V supply voltage and draws a maximum supply current of 5mA. Frequency stability is specified at ±280ppb over the operating temperature range of -40°C to +85°C. The component is housed in a 4-SMD, No Lead package with dimensions of 7.00mm x 5.00mm.

Feature Summary

• Temperature compensated crystal oscillator design for stable frequency generation
• CMOS output interface compatible with standard digital logic
• Compact surface-mount package suitable for space-constrained designs

Applications

• Industrial control systems requiring precise timing
• Automotive electronics operating in wide temperature ranges
• Communication equipment needing stable clock signals

Procurement Notes

Verify the specific suffix 'BP-T' against official QST documentation to confirm pinout configuration and lead-free status. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain the stated ±280ppb frequency stability. Cross-reference the 4-SMD package dimensions with PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a stable 20 MHz clock source is required in compact applications. The CMOS output simplifies integration with digital circuits without additional buffering. Consider the ±280ppb stability specification for precision timing needs. Verify that the 3.3V supply voltage aligns with the system power architecture and that the 5mA current draw fits within power budget constraints.

Part Context

This part belongs to the QTS750C series of TCXOs from QST. The series offers various frequency options including 12.8 MHz, 25 MHz, and 38.88 MHz variants. All models share similar package dimensions and electrical characteristics, differing primarily in nominal frequency and specific stability metrics defined in their respective datasheets.

Replacement Considerations

Direct substitutes include other QST TCXO models in the same package family, such as QTS750C-25.000MBO-T or QTS750C-12.800MBP-T, provided the frequency difference is acceptable. Verify pin compatibility and electrical specifications before substitution.
